The city’s confusing recycling rules should become a little more transparent to everyone tomorrow with the return of glass pickups.

Full, weekly recycling pickups will resume after two years of bewildering changes that left many residents wondering what gets put in the recycling bin and what gets tossed in the regular garbage.

Lawmakers toasted the return of full-scale recycling yesterday at City Hall.

“We’re here to celebrate the rebirth of recycling, which is rising like the phoenix out of the ashes,” said City Councilman Mike McMahon (D-S.I.), chairman of the Committee on Sanitation and Solid Waste Management.

McMahon said city officials, while doing more than they’ve ever done to promote recycling, still are not doing enough.

He suggested Mayor Bloomberg promote recycling at every opportunity, just as he does the 311 hot line.

“They’re not doing enough … A little money invested in education would save a lot of money in the long run,” McMahon said.

But city officials defended their efforts, which include a $4 million newspaper-ad campaign.

“We’re also sending out a mailer to every household,” said Sanitation spokesman Vito Turso.

“We’ll be placing posters on the sides of our 2,000 collection trucks. We have information on our Web site, and 311 [operators] have been well briefed on the changes.”

Faced with a severe budget gap, the Bloomberg administration suspended glass and plastic recycling in 2002 to save $40 million.

A year later, plastic recycling resumed.

But all the pickups were on an alternate-week schedule.

Officials say they expect this week’s transition to be smoother, since residents won’t have to figure out which week to leave out the recyclables.

The $25 summons for failure to sort out glass won’t be levied for another 60 days.

Turso said city officials have negotiated a $51-a-ton rate for disposing of recyclables, about half the previous rate.

“While it was a painful suspension it wound up having a bright side because recycling costs were halved,” Turso said.

McMahon said the city could not “go on the way it has been for the last decade, mismanaging its solid-waste program. Recycling is a very important part of that.”
